I installed the app on my Galaxy Nexus and it works as advertised. I found it easy to set up my monthly data limit — unofficially 2 GB with a Straight Talk SIM — and there’s an integrated speed test function for both Wi-Fi and 3G/4G connections. You can view data usage by connection type and by historical time: Last day, 7 days, 30 days and since you installed the Data Saver app. The software is supposed to offer data saving suggestions at the end of a billing cycle but since I just added the app, I can’t speak to what it might say.

Included with the app are two optional widgets. One is the same speed test feature found in the app, while the other is a data savings meter, showing how much data you’ve used in the current cycle. All of the information found in the widgets are readily accessible in the app, but the widgets provide quicker access for those that want it.

That aside, the app will also connect you to a Wi-Fi hotspot on Devicescape’s virtual network if you’re in range of one. You can enable this to be an auto-connect or simply a notification of network availability. And the app can store Wi-Fi network credentials for hotspots you connect to often, i.e.: at work, school or on the road.

Overall, DataSaver looks handy, but I question the long-term viability of it. Why? Mainly because with Android 4.0, introduced in October, Google added a native Data Usage feature that replicates much of what DataSaver offers. Granted, few Android devices are running 4.0 today, but new devices are coming with the latest Google software and we’re finally seeing a roll out of Android 4.0 to older devices.
